Take a look at the simple math puzzle below and see what you make of it. Also, check the clock before you start. How fast can you do this?

Now to the brainteaser – can you figure out the answer? Try to think back on the mathematical rules!

To help you along, we’ve provided 3 solutions.

We can already reveal that “C: Something else” can be discarded.

So either 24 or 154 is correct. But which one?

If you remember, multiplication is always done before addition. Therefore:
